Knock Out

A sexy transformer who likes the way he looks in steel-belted radials. He attempted to join the Autobots in the television series Transformers - Prime on the last episode only to be rejected, but in the movie he was accepted. Knock Out is very concerned about keeping his finish clean and his paint looking fabulous.

Knock Out is not only an automobile, but an automobile enthusiast.
